3 Which brain region is heavily involved in decision-making and impulse control, and is often impacted by long-term substance use?
  • A Prefrontal cortex
  • B Cerebellum
  • C Brain stem
  • D Occipital lobe
4 What does the term 'dependence' refer to in the context of addiction science?
  • A Only the presence of physical symptoms
  • B The inability to stop using a substance
  • C A state where the body has adapted to a substance's presence
  • D The social desire to use a drug
5 Which of the following is considered a primary 'reward' pathway in the brain?

  • B Visual cortex pathway
  • C Spinal cord pathway
  • D Auditory pathway
6 What happens during the 'withdrawal' phase of addiction?
  • A The brain increases dopamine production
  • B Physical and mental symptoms occur upon cessation of use
  • C The person feels no desire for the substance
  • D Tolerance levels reach their peak
7 Which organ is the primary site for the metabolism of most consumed substances?
  • A Heart
  • B Lungs
  • C Liver

8 Chronic exposure to addictive substances can lead to changes in the strength of connections between neurons. What is this process called?
  • A Neuroplasticity
  • B Cellular atrophy
  • C Myelination
  • D Synaptic pruning
9 What is the primary function of the 'ventral tegmental area' (VTA) in the brain?
  • A Regulating body temperature
  • B Processing memories
  • C Producing dopamine for the reward system
  • D Controlling motor coordination
10 In addiction science, what does 'craving' refer to?
  • A The physical pain of withdrawal
  • B An intense, urgent desire for the substance
  • C The act of consuming a substance
  • D A lack of knowledge about drug effects
11 Which neurotransmitter system is typically inhibited by alcohol consumption?
  • A Glutamate
  • B Dopamine
  • C Serotonin
  • D Norepinephrine
12 What does the 'incentive salience' theory suggest about addiction?
  • A Drugs become less rewarding over time
  • B Addiction is purely a social choice
  • C Cues associated with a drug trigger intense motivation to use
  • D Addiction is unrelated to the brain's reward system

  • A Achieving a new, stable baseline due to chronic substance use
  • B Returning to perfect health immediately
  • C A short-term change that does not affect biology
  • D The elimination of all drug memories
17 What is 'homeostasis' in biological terms as it relates to addiction?
  • A The brain's effort to maintain internal balance
  • B The process of increasing drug dosage
  • C The genetic predisposition to addiction
  • D The chemical composition of a drug
18 How do addictive substances typically affect synaptic transmission?
  • A By blocking the brain from receiving oxygen
  • B By altering the release or reuptake of neurotransmitters
  • C By physically destroying neurons
  • D By preventing blood from reaching the brain
19 What characterizes 'compulsive' drug seeking in addiction?
  • A Intentional, infrequent use
  • B Use despite negative consequences
